CHARLES M. MITCHELL,OF WATERBURY, CONNECTICUT.

Letters-Patent No. 90,287, dated May 18, 1869.

To all whom it may concern.-

Be it known that 1, CHARLES M. MITCHELL, of Waterbury, in the county ofNew Haven, and State of Connecticut, have invented a new Improvement inGlobe-Holder for Gas-Fixtures; and I do hereby declare the following,when taken in connection with the accompanying drawings, and the lettersof rei'erence marked thereon, to be a full, clear,and exact descriptionof the same, and which said drawings constitute part of thisspecification, and represent in- Figure 1, a top view;

Figure 2, aside view; and in Figure 3, a section on line a: 2:.

This. invention relates to an improvement in the construction of theholder for gas-fixtures for supporting the globe.

Heretofore these holders have been formed, as seen in fig. 4, with twolips, s 3, turned inward, and a setscrew, t, upon the opposite side.

These lips, which are cut from the same metal as the body of the holder,unavoidably cause considerable waste of metal, and the adjustment of theglobe by means'of the set-screw is necessarily very imperfeet, and if,perchance, the globe is set upon the holder without the screw beingturned upon it, the globe is easily thrown from its place, consequentlybroken, and if the screwbe turned too tight, then, as the globe expands,it unavoidably cracks.

To overcome these objections is the object of my invention, whichconsists in combining upon a holder three springs, each of similar form,so as to receive thehase of the globe, securely hold it in its place,and yield to any expansion or contraction of the globe.

In order to the clear understanding of my invention, I will fullydescribe the same as illustrated in the accompanying drawings.

A is the body of the holder, of the usual or any desired form,constructed so as to be secured to the burner, by preference by threearms, B B B, extending from a central ring to an outer.

To each of these arms, or at any point, I attach a spring, 0, preferringthree springs, as producing the best result. The inner end of the saidspring is riveted or secured to the arm at any convenient point, so asto leave the remaining portion free.

The outer end of the springs I bend, as seen at D, fig. 3, into suchform that the globe may be easily depressed into the grasp of the saidsprings, and by the said springs be securely held into position, thesprings yielding to any expansion or contraction of the globe, andconforming to the different size of the base of the diflerent globes.

By this construction all the difficulties attending the securing of theglobes to the gas-fixtures is entirely overcome, also dispensing withthe screw, which is done at no additional cost.

I do not broadly claim the arrangement in a globeholder of a spring tograsp and hold the shade, as such, I am aware, is not new, and I amaware of the patent of Thomas Hay, January 26,1869, and claim nothingshown therein as my invention.

Having fully described my invention,-

- What I claim as new and useful, and desire to secure by LettersPatent, is-- The herein-described globe-holder, as an article ofmanufacture, consisting of the three springs 0, arranged and secured tothe base substantially as described.
